where does the request body of store come from?

[handhikadj]

grapesjs sends this data.
how do I get the value of the json?

const gjsData = {
                        'gjs-assets': JSON.stringify(this.editor.AssetManager.getAll().map(asset => asset.attributes)), // not sure if this is right
                        'gjs-css': this.editor.getCss(),
                        'gjs-styles': JSON.stringify(this.editor.Styles.getAll()), // not sure if this is right
                        'gjs-html': this.editor.getHtml(),
                        // 'gjs-components': this.editor.getComponents(),
 }
